JAMES RILEY, OF PATRICROFT, ENGLAND.

STENTER-CLIP.

Application filed January 15, 1906.

To all 'whom it may concern:

Be it known that I, JAMES RILEY, a subject of the King of Great Britain and Ireland, and a resident of Patricroft, in the county of Lancaster, England, engineer, provements in stenter-Clips, of which is a specification.

This invention relates to improvements in stenter clips for use in connection with stentering, stretching, fabric-drying and similar machines, and particularly relates to that class of clip in which a pivoted jaw is employed to form the main portion of the gripping or retaining means, the object of the present invention being to provide an improved clip by which the thinnest and thickest of fabrics can be securely held during the processes referred to above.

My invention consists essentially in constructing a stenter clip with a pivoted jaw and with a jaw of a rotatable character in conjunction therewith, the two acting together in such a way as to securely grip the fabric.

My invention will be fully described with reference to the accompanying drawings in which Figure 1 is an end elevation of the clip, in section, showing the character of my invention, Fig. 2 front elevation of same with a portion broken away and Fig. 3 plan.

In carrying out my invention I construct the main the following body a of the clip in any suitable form so that each link or portion is adapted to be readily connected together in the form of a chain as will be well understood and from the upper portion of the jaw I provide an extending arm'or arms b in which is located a stationary or loose pin o adapted to have mounted upon it or carried by it a loose jaw d, the free end or engaging portion of which is preferably formed with a plain surface e, though I would have it understood that the surface may be grooved, serrated, or roughened, if necessary. In conjunction with the loose pivoted jaw I employ a second gripping surface in place of the usual fixed plain surface or plate and which second jaw is capable of a rotatory or circular movement, or a movement in a curved path. This second jaw preferably consists of a roller f of approximately the same length as the clip body. The roller is preferably grooved or iiuted and is supported in a channel or grooved portion g formed in the main body of thefclip below the loose pivoted jaw. The roller is held in position longitudinally in any suitable manner; but, preferably, by forming therein one or more grooves h of an annular character,htransversely, preferably two with which setscrews 'i passed through the body of the clip, may engage. These said screws may, however, be dispensed with or be used in conjunction with two other setscrews j passed through the base of the chan- Specication of Letters Patent.

neled portion of the clip, the latter screws being adapted to support the gripping surface from the bottom, being arranged to enable the said gripping surface to be'raised or lowered with relation to the pivoted jaw so that any necessary adjustment can be made to take up any wear of the parts. j

The free end or engaging portion of the pivoted jaw d may be arranged at an angle to its approximately vertical face k so that when in contact with the cloth between it and the bottom gripping surface, the tendency is for the pull on the cloth to increase the gripping pressure. The pivoted jaw d may be lifted out of contact with the cloth by any usual means and allowed to come in contact with the cloth in the ordinary way. The lifting means shown in the drawings consist of an arm Z designed to come in contact with a stationary projection on the stenter machine as will be well understood, such 'projection causing the jaw to be lifted from the full line to the broken line position and allowed to drop from the broken line position to the full line position as required.

I may employ in conjunction with the pivoted jaw a usual pivoted lever fm the free' end or ends n of `which rest upon the cloth as the pivoted jaw is descending to the gripping position, the said lever being provided with an arm o resting on the rear of the pivoted jaw so that when the latter is being lifted up to the broken line position, the lever m rises at the same time while it also falls at the same time as the gripping position is being reached, the ends n passing through slots p in the main body of the clip.

By `constructing a clip as described I am not only enabled to deal with the various thicknesses of fabric but to do so without causing any injury thereto. The rotatable roller may be made of any suitable material.

What I claim as my invention and desire to secure by Letters Patent is 1. In a stenter clip the provision o1' a lower gripping surface consisting of a loosely mounted and rotatable roller and an upper gripping surface acting in conjunction therewith substantially as described.

2. In a stenter clip the provision of a lower gripping surface consisting of a loosely mounted and rotatable roller having a iluted periphery and an upper gripping surface acting in conjunction therewith substantially as described.

3. In a stenter clip the provision of a lower gripping surface consisting of a loosely mounted and rotatable roller and means for adjusting said roller an upper gripping surface acting in conjunction therewith substantially as described.

4. In a stenter clip the provslon of a lower grippingl 5. In a stenter clip the provision of a lower gripping surface consisting of a loosely mounted and rotatable roller and a channeled bracket for supporting said roller an upper gripping surface acting in conjunction therewith substantially as described.

G. In a stenter clip the combination of a lower gripping surface consisting of a loosely mounted and rotatable roller with a pivoted jaw carried by the main body of the clip substantially as described.

7. In a stenter clip, the provision of a lower gripping surface consisting of a loosely mounted and rotatable rolle]l and a pivotally supported upper gripping surface acting in conjunction therewith.

In testimony whereof I have hereunto set my hand in the presence of two Witnesses.

JAMES RILEY.
